如何在titan图DB中的顶点属性上执行通配符搜索？

Question

I am using blueprints api to query titan graph database. I am in a situation where I need to perform wild card search on a vertex property. Is there a way to query a vertex with its property with a wildcard? something similar to "PropertyName like '%asdf%' " in relational database.

Answer 1

You can read about how to do string-based searches here:

https://github.com/thinkaurelius/titan/wiki/Full-Text-and-String-Search#string-search

In your case you would likely need to use a Text.REGEX based search as you want to evaluate both sides of the string. You would execute this with the Blueprints API using the Query API and would be something like:

graph.query().has("name",Text.REGEX,".*asdf.*").vertices()

在Gremlin v2中我这样做：

g.v.has('name',REGEX,'.*asdf.*').map
